I have a crawlspace with a horizontal furnace -> coil placement. The coil needs to be replaced, but the tech cannot find any on the market the same size (the coil is an A-type, 20 yrs old).
Current Config: Horizontal Return -> Filter -> Furnace -> 90 degree Bend -> A Coil (Link to Image of Config:
I had one tech come in and say that he can alter the configuration to be horizontal "pull-through".
Return -> Filter -> Flat Coil -> Furnace -> 90 degree bend (Link to Image of New Config:
So, my question is: Will this new config cause problems? I've read a couple conflicting statements like:
"The evaporator coil must be installed in the discharge (supply) air of a gas or oil furnace. Do not install an evaporator coil in the return air, or excessive condensation will occur within the furnace."
Then the second image was taken from a site that recommends the new setup for better "thermodynamics" of pulling moisture from the air via a "pull-through" method.
Any help would be appreciated. I've gotten two quotes for fixing my unit:
- Pull-through - 0
- Full replacement of furnace + coil (bc they can't fit a coil after furnace) - ,700
Thanks!
